There’s an “Expiration Date” on Supplier/Purchase/Misc Supplier Info which stops POs being raised.  There’s an “Inactive Field” on Supplier/Invoice/General which stops invoices being processed.  
 This means you can stop new POs being raised whilst still being able to process invoices for previously raised/received POs.
 (Don’t forget to update “Supplier for Purchase Part” records!)
 As a default, these fields don’t appear on (overview) “Suppliers” screen but you could add these as custom fields thus being able to report by running a query where either of these fields is not null.
